As always, westerners leave in an information bubble. Chechnya was always a part of Russia. It was a civil war. Ukraine was always a part of Russia until 1991, btw, there was never a separate country called "Ukraine" before 1991 - you can easily find that even in Western history books, although I'm sure they'll be rewritten in some way soon, if not already.
Georgia launched attack in 2008, it is easily confirmed by:
1. News from that time (there was a several days delay between Georgia attack and when Medvedev decided to respond, during that time Putin called a press conference and said: "Georgia has started an attack and is bombing civilians, but Western press is silent about it". You can still find recordings of that press conference on video hosting sites, I believe.
2. There was an independent EU investigation that also confirmed that Georgia started the attack in 2008.
3. Last year Georgian government itself confirmed that they were attacking first.
It never cease to amaze me in what distorted information reality people live.
BTW, it's for the best, because it was the reason why West could coerce Georgia into starting a war in 2008. All the population, including the top politics lived in an alternative reality, so they basically said to Georgia: "Russia is weak and corrupt, they have no army, no weapons, they have only shovels, and even their shovels are rusty. So you'll easily get what you want without any resistance."
Actually, more or less the same repeated in 2022. Just read HN comments from 2022: "Russians are surrendering by tens of thousands a day, they don't want to fight with warm and welcoming and kind Ukrainian soldiers", "Ukraine burns thousands of Russian tanks and armored vehicles a day: here's a photo proof", etc, etc.
So this distortion of reality works the other way round, when West bases its actions on it. There are lies from top to bottom, and then everyone makes all kinds of decisions based on those lies.
